ZB'OEZN S. BRADLEY, OF DELAWARE, OHIO, ASSIGNOR 0F ONE-HALF TO WILLIAM WATTEBfi, OF DELAWARE, OHIO.

ORCHARD-HEATER.

Application filed May 13, 1915.

Z '0 all whom it may concern Be it known that 1, JOHN S. BRADLEY, citizen of the United States, residing at Delaware, in the county of Delaware and State of Ohio, have invented certain new and useful Improvements. in Orchard-Heaters, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to orchard heaters,

and has for its principal object the production of a simple and eilicient means for producing a dense cloud of smoke for the purpose of reducing the chill in an orchard and thereby preventing the fruit from becoming frozen or frost-bitten.

Another object of this invention is the production of an orchard heater wherein the burner is so constructed as to carry a quantity of *charcoal upon which the oil may be passed so that upon the igniting thereof a dense cloud of smoke may be produced.

Another object of this invention is the production of an orchard heater wherein the reservoir which carries the oil is provided with a valve mechanism so constructed as to increase or diminish the flow of oil as the occasion may require.

With these and other objects in View this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed. 4 y

In the accompanying drawing: Figure 1 is a side elevation of the orchard heater partly broken away and partly in'section. Fig. 2 is a fragmentary sectional view through a portion of the orchard heater showing the specific construction of the valve mechanism used in regulating the flow of the oil. Fig. 3 is a top plan view of the burner showing the sectional cover partly broken away. Fig. i is a vertical section through burner. Fig. 5 is a section taken on the line 5-5 of Fig. 1.

Referring to the accompanying drawing by numerals it will be seen that the orchard heater comprises a reservoir 1 which is adapted to be supported upon a supporting ring 2. This reservoir 1 has an open top which is adapted to be closed by the removable cover 2 which is concaved toward itscentral portionsm-as to provide a Specification of Letters Patent.

adapted to be closed by means of the removable plug. 1 whereby when so desired the reservoir may be filled with oil, at which time the-plugd may be placed so as to close the opening 3 and prevent the passage of dirt or other refuse into the interior of the reservoir.

A short pipe 5 isthreaded into engagement with the collar 6 carried by the reservoir 1, while the valve body 7 is mounted upon the outer end of this pipe. This-valve body 7 is provided with a bore 8 connecting with the pocket 9. A curved passage 10 connects with the lower portions of the pocket 9 and extends to connect with the outer portions of the neck 11 within which one end of the feed pipe 12 is detachably mounted. A short pipe 13 is also carried by a collar 1+1 adjacent the upper portions of the reservoir 1 so as to be carried by the thimble 15 engaging the T-joint l6. This T-joint is also adapted to carry a sec ond thimble 17 for the purpose of support ing an externally threaded air pipe 18. A plug 19 is used for the purposeof closing the outer end of the T-joint 16 whereby A stem 21 is secured to the outer end of the feed pipe 12 by any suitable connection as illustrated at 22. This stem 21 is secured to the base portion 23 of the burner 24. This base 23 is constructed so as to consti-. tute a cup-like member having its upper portion opened. A circular wall 25 is carried. within the burner 24 at a spaced distance from the inner side portions of the burner. This wall 25 is mounted upon the connecting portions 26 of the burner 21 and base, 23. Therefore, sufficient space is pro vided for the mounting of the plate 27 which is provided with a plurality of openings 28. This plate is used for preventing the passage of large quantities of dirt or refuse into the cup and preventing the same from eficiently operating. A= quantity of charcoal 29 is carried within the spaces batw the inner pass into the charcoal whereby when the oil is ignited the charcoal will act as a smudge for producing a quantity of smoke for .pre-

1 venting or reducing the chill in an orchard.

When the device is in operation it is necessary to place a quantity of oil within the reservoir' 1. The sleeve may then be rotated so as to be moved upwardly upon the air pipe 18 as shown in Fig. 2. This 1 action will provide a free passage through the pipe 5, bore 8, pocket 9 and passage 10 whereby the oil may pass therethrough into the feed pipe 12. From this pipe it will pass through the stem 21 into the base or cup 23 so as to be discharged through the apertures 28 and openings 30 upon the charcoal 29. It is, of course,-obvious that the quantity of oil supplied may be increased or diminished as desired by the adjustment of the sleeve 20 upon the air pipe 18. If the sleeve is rotated so as to move downwardly into the pocket, the supply of oil will be diminished or" upon the engagement of the sleeve and the lower portions of the pocket 9 thesupply of oil will be entirely out oil; It will be'seen that the inner portions of the passage 10 are in direct alinement with the inner portions of the sleeve 20, and thereby 'the sleeve in fitting against the bottom of the pocket 9 will preventthe passage of oil thereinto. As the sleeve is rotated so, as to move upwardly upon the air pipe 18 sufficient space is provided upon the side portions of the sleeve 20 for the passage of air into the pocket 9. The air will then pass around into the interior of the sleeve 20, through the air pipe 18, the T-joint 16 and short pipe 13 into the interior of the reservoir 1 for preventing a suction therein, and allowing free passage of the air therefrom.

When it is desired to protect the inner portions of the burner 24:, the sectional top 31 carried by the bolt 32 may be swung to a closed position as indicated in Figs. 1 and 4, this inward movement being limited by the over-hanging lips 33. It will further be seen that the reservoir 1 is provided with an ear 34 through which one end of the lifting rod 35 may pass, while the opposite end of the lifting rod 35 is carried by the eye 36 of the wound strand 37 mounted upon the neck 11 of the valve body 7 as shown at 38. A grip 39 may be carried 'upon this rod adjacent the central portions, whereby the heater may be easily lifted and carried from place to place as the occasion may require.

From the foregoing description it will be seen that a very simple and eflicient'orchard heater has been produced wherein a valve is provided for the purpose of increasing or diminishing the flow of oil from the reservoir as the occasion may require, while an eflicient burner has been provided which will produce a quantity of smoke when the oil which is fed thereto is ignited.
